Does WP Ghost Work with All Cache Plugins?

Yes. WP Ghost is tested and compatible with all major cache and performance plugins. The WP Ghost team periodically tests compatibility with over 25 caching plugins and automatically detects the most popular ones to create URL mappings for their cache directories. If your cache plugin isn’t on the tested list, it most likely still works. Just enable “Change Paths in Cached Files” and clear your cache after saving WP Ghost settings.

Which Cache Plugins Has WP Ghost Been Tested With?

WP Ghost is periodically tested with: WP Rocket, W3 Total Cache, WP Super Cache, WP Fastest Cache, LiteSpeed Cache, Autoptimize, Cache Enabler, CDN Enabler, Breeze Cache, Comet Cache, Hummingbird, Hyper Cache, Powered Cache, NitroPack, Bunny CDN, Jetpack (Site Accelerator), Cache-Control, JCH Optimize 3, SWIS Performance, WP Speed of Light, SiteGround Optimizer, Rabbit Loader Cache, and FlyingPress.

For the complete and current list, see the compatible plugins list.

Why Do Cache Plugins Need Special Attention?

Cache plugins save pre-rendered HTML files containing the actual paths to your CSS, JavaScript, plugins, themes, and uploads. When WP Ghost changes these paths, live page output uses the new custom paths, but cached HTML files still reference the old WordPress defaults until they’re regenerated. Without coordination, visitors would see cached pages exposing /wp-content/plugins/ and /wp-content/themes/ even though WP Ghost is active.

Additionally, many cache plugins combine and minify CSS and JavaScript files into new files stored in their own cache directories. WP Ghost needs to know about these directories to rewrite the paths inside them.

How Do I Configure WP Ghost to Work with My Cache Plugin?

Two steps handle most cache plugin setups:

Step 1: Enable Change Paths in Cached Files. Go to WP Ghost > Tweaks > Hide Options and switch on Change Paths in Cached Files. This tells WP Ghost to rewrite paths inside your cache plugin’s generated files so they reference your custom paths instead of the WordPress defaults. Click Save.

Step 2: Clear your cache. After saving WP Ghost settings, purge your cache plugin’s cache completely. This forces new cached files to be generated with the correct paths. Do this after every WP Ghost path change.

WP Ghost automatically detects popular cache plugins (WP Rocket, LiteSpeed Cache, Autoptimize, and others) and creates URL mappings for their cache directories. You don’t need to configure these manually. For specific setup guides, see the WP Ghost and WP Rocket guide or the WP Ghost and LiteSpeed Cache guide.

What If My Cache Plugin Isn’t on the Tested List?

WP Ghost has been tested with over 1,000 plugins and themes. If your cache plugin isn’t on the list, it doesn’t mean there’s an incompatibility. WP Ghost doesn’t physically change any files, so most plugins work without issues. Enable Change Paths in Cached Files, clear your cache, and verify in a private browser that the new paths appear in the page source. If you find a compatibility issue, contact WP Ghost support and the team will work to add compatibility.

Frequently Asked Questions

Do I need to clear my cache every time I save WP Ghost settings?

Only when you change paths. Cached files contain path references that won’t update until the cache is regenerated. After any path change in WP Ghost, clear your cache plugin’s cache, any server-level cache (Varnish, Nginx FastCGI), and your CDN cache if applicable.

Old WordPress paths still appear in the page source after enabling WP Ghost. Why?

Almost always a caching issue. Clear all caches (browser, plugin, server, CDN), then check again in a private browser window. If old paths only appear in combined/minified CSS or JS files, make sure Change Paths in Cached Files is enabled. If it’s already on, try regenerating the minified files through your cache plugin’s purge option.

Does WP Ghost slow down my cached site?

No. WP Ghost’s path rewriting happens at the server level through rewrite rules (Apache/LiteSpeed) or during output buffering (Nginx/WordPress). Once your cache plugin generates the cached files with the correct paths, visitors get served directly from the cache with no extra processing. WP Ghost actually reduces server load by blocking malicious bot traffic before it reaches PHP.

Does WP Ghost modify WordPress core files?

No. WP Ghost uses server rewrite rules and WordPress filters. No core files, theme files, or plugin files are modified. Compatibility with cache plugins is maintained through URL mapping and output buffering, not file changes. Deactivating WP Ghost restores all defaults instantly.
